Procedure
Copied from the source record, unedited
To 8-chloro-4-methyl-2-(4-methylthiazol-2-yl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (120 mg, 0.41 mmol) in DME (3 mL) were 6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-amine (83 mg, 0.41 mmol), cesium carbonate (198 mg, 0.61 mmol), 2-(Dicyclohexylphosphino)biphenyl (14.22 mg, 0.04 mmol) and Palladium acetate (9.11 mg, 0.04 mmol) added. The reaction was heated to 110°C for 180 min under N2 atmosphere. The solids were filtered off and washed with DCM, the solvents were evaporated and the crude product was purified by silica flash chromatography, MeOH, 0-10%, in DCM yielding N-(6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl)-4-methyl-2-(4-methylthiazol-2-yl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-amine (20.00 mg, 10.63 %)

How to read this record
This is one experiment, not a rule. It says that on one occasion these species were combined under these conditions and this came out. It does not say the reaction will give the same result on your substrate, and nothing on the page has been generalised into a claim that it would.
The pathway is a separate question, kept on separate pages. A mechanism here is the canonical arrow pushing for a class, run on real structures and labelled rule-derived. It is not evidence, and this record is not a mechanism.
